Flower's technical outline of dragon slaying is an epic task book (both warriors and paladins can take on tasks). Right-click the technical outline of dragon slaying in Lochiel, accept the task of technical outline of dragon slaying in Lochiel, and then hand in the task to NPC "Ledro, Scholar" in the unlucky library. After handing in the task, start a dialogue with this NPC (that is, click on the dialogue, and then a new task will be picked up). Then I kept sending and receiving tasks here, and finally got the task of "casting Quesela (team)" (note: at this time, your bag should have purple task props of "Unhardened Ancient Blade"). At this time, you need to insert the task into the ground and get the task when Onyxia, the team copy, defeats Onyxia in the nest. You'll get a task reward when you hand in the task, Quesella.
